What is the chemical formula for proteins? + Example - Socratic
2017年9月26日 · If you know what proteins are made of, you should know just how many atoms they contain. Proteins are humungous macromolecules, rarely represented by chemical formulas. Proteins are made of amino acid sequences bonded together into secondary structures which interact to form three dimensional tertiary structures which further interact to form quaternary …
What is the chemical composition of proteins? - Socratic
2015年10月30日 · There are 20 different amino acids which make up proteins. Each amino acid consists of a central carbon. The central carbon is bonded to an amine group (#NH_2#), a carboxyl group (COOH), a hydrogen atom and an R group.
How would you calculate the molecular weight of a protein?
2016年7月30日 · You would need to find its chemical formula, then determine its molecular weight as usual. See below for an example. Example Hemoglobin is the protein in red blood cells that carries oxygen throughout the body.
A component of protein called serine has an approximate
2016年3月2日 · "C"_3"H"_7"NO"_3 Here's a great example of a problem that allows you to use a bit of logic to find the molecular formula first, then backtrack to find the empirical formula. Notice that you are given the molar mass of serine, which is said to be approximately equal to "100 g mol"^(-1). That means that you can expect the actual molar mass of serine to be either a little …
How can you tell whether the chemical formula for a compound
2015年11月22日 · if it contains carbon, hydrogen and oxygen only in the ratio of 1:2:1, then it is a carbohydrate. If it contains carbon, hydrogen, oxygen and nitrogen, then it might be a protein. Proteins are made of amino acids connected together. each amino acid has a carbon atom connected to four groups which are COOH, NH2, H and a variable group given the symbol R. …
How do you calculate concentration from absorbance? - Socratic
2014年3月18日 · You will use Beer's law. A = εmCl The basic idea here is to use a graph plotting Absorbance vs. Concentration of known solutions. Once you have that you can compare the absorbance value of an unknown sample to figure out its concentration. You will be applying Beer's law to calculate the concentration. The equation for Beer's law is: A = εmCl …
An organic compound contains only the elements carbon
2016年12月8日 · Yes, it could be a carbohydrate No, it can not be a protein. A carbohydrate has only Carbon, Hydrogen and Oxygen, with the hydrogen and oxygen in the ratio 2:1. Examples are glucose C_6H_12O_6 and table sugar C_12H_22O_11 A protein is made of amino acids. Amino acids have an amino group which is -NH_2. So without nitrogen atoms the compound can not …
What is the relationship between monomers and polymers? Give
2018年6月21日 · Monomers are small, simple molecules that can be joined together to form polymers. Monomers can simply be referred to as smaller sub-units of polymers. Through a process called polymerization, monomers are are linked together into long repeating chains to form polymers Here's a quick diagram i drew using ms paint to illustrate my point. Proteins are …
Why are amino acids chiral? + Example - Socratic
2014年10月28日 · All amino acids except glycine are chiral because they all contain at least one chiral centre. The general formula for an amino acid is The central carbon has four different groups attached. So the compound can exist as a pair of nonsuperimposable mirror images. Thus, we can have D- and L-isomers of amino acids. A rule of thumb for determining the D/L …
How would you be able to structurally tell if a molecule is
2016年8月31日 · Carbohydrates are polyhydroxy aldehydes or ketones or compounds which yield these on hydrolysis. The most common component of lipids in the body are the fatty acids. These are aliphatic carboxylic acids and have the general formula R-CO-OH where COOH [ carboxylic group ] represents the functional group. Carbohydrates basic structure of aldehydes and …
