What is the description of protein?

A protein is a naturally occurring, extremely complex substance that consists of amino acid residues joined by peptide bonds. Proteins are present in all living organisms and include many essential biological compounds such as enzymes, hormones, and antibodies.

How do we classify proteins?

Proteins can be classified into groups according to sequence or structural similarity. These groups often contain well characterised proteins whose function is known. Thus, when a novel protein is identified, its functional properties can be proposed based on the group to which it is predicted to belong.

What are derived proteins?

Derived proteins. These are proteins derived by partial to complete hydrolysis from the simple or conjugated proteins by the action of acids, alkalies or enzymes. They include two types of derivatives, primary-derived proteins and secondary-derived proteins.

Which of the listed proteins are simple?

Proteins can be simple (e.g., albumin, globulin, zeatin, histones, prolamines etc) or conjugated (e.g., nucleoprotein, i.e., protein conjugated with nucleic acids; glycoprotein, i.e., protein conjugated with carbohydrates, metalloprotein, i.e., metal conjugated with protein as in ferritin, lipoprotein, i.e., lipid …

What elements are proteins made of quizlet?

Proteins are the most complex biological molecules because they are made of five different elements: carbon, hydrogen, oxygen, nitrogen, and sulfur. Compared to other biological molecules, which may only contain up to three or four other elements. Draw the structure of a general amino acid.

How many proteins are in a gene?

six proteins

What proteins do genes code for?

A gene is the section of DNA required to produce one protein. Genes are typically hundreds or thousands of base pairs in length because they code for proteins made of hundreds or thousands of amino acids. Most genes contain the information needed to make functional molecules called proteins.

Why do humans have more proteins than genes?

Protein number can exceed gene number in eukaryotes, in part because cells can produce different RNA variants from the same genes by “alternative splicing”, which can create mRNAs that code different combinations of substructures from same gene! Alternate splicing is discussed in detail in a later chapter).
