Heat convection is a mode of heat transfer by the mass motion of a fluid such as air. Heat convection occurs to the surface of an object where the surrounding fluid of object is heated and moved energy away from the source of heat.
Glucose binds to the glycogenin protein to form the glycogen polymer. Glycogen synthase uses UDP glucose as the substrate for polymerization via (1-4) bonds. The branching enzyme has two distinct functions: it breaks the linear chain and forms a branch using a (1-6) linkage.

What are nucleotides?</h3>
A nucleotide is the primary component of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA), a phosphate group, and a nitrogen-containing base. DNA nucleotides include adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the nucleotide uracil (U) replaces thymine. Polymeric DNA and RNA molecules are composed of long strands of nucleotides.
