What is the functional group of a protein molecule quizlet?
Proteins are composed of amino acids joined together. Which of the following is not attached to the central carbon atom in an amino acid? The central carbon atom in an amino acid is bonded to an amino functional group, a carboxyl functional group, a side chain, and hydrogen. You just studied 67 terms!
What are the 4 functional proteins?
There are four structural levels of protein: primary, secondary, tertiary, and quaternary.
What are the functional groups in amino acids?
Amino acids are natural compounds composed of amine (–NH2) and carboxylic acid (–COOH) functional groups, linked to the same carbon atom.
What is an accurate description of proteins?
Which of the following statements is an accurate description of proteins? The primary structure of a protein is the order of amino acids in a polypeptide, as coded for in the DNA of a gene. This protein illustrates all four levels of protein structure.
Is alcohol a functional group?
Classification of alcohols: Alcohols are a common functional group (-OH). They can be classified as primary, secondary, or tertiary, depending on how many carbon atoms the central carbon is attached to.
What are 2 functional groups in amino acids?
An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid. The term amino acid is short for α-amino [alpha-amino] carboxylic acid.
How do you classify amino acids?
Based on the variable group, amino acids can be classified into four categories: nonpolar, polar, negatively charged, and positively charged. Of the set of twenty amino acids, eleven can be made naturally by the body and are termed nonessential amino acids.
What are the different types of functional groups?
Functional groups are groups of atoms in hydrocarbons which are responsible for their chemical properties. The types of functional groups include halocarbons, alcohols, ethers, aminoss, aldehydes, ketones, carboxyllic acids and esters. These functional groups are bound to a hydrocarbon structure denoted R.
What are the functional groups in biology?
Properties of Functional Groups. A functional group can participate in specific chemical reactions. Some of the important functional groups in biological molecules include: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl groups. These groups play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids.
What is amino acid functional groups?
Amino acids are organic compounds which contain both an amino group and a carboxyl group. They are distinguished by the attached functional group R. Of the twenty amino acids that make up proteins, six of them have acid or base R-groups .
What is the structure of an amino group?
The basic atomic structure of amino acids consists of a carbon bound to an amine (-NH2) group and a carboxylic acid (-COOH) group, along with a ‘side chain’. This structure is also the reason why the molecules are named ‘amino acids’.
